ABSTRACT:
A seal and closure member of elastomeric material adapted to be cast in situ and comprising a cylindrical body portion and an integral frusto-conical skirt therewithin. A radially outwardly extending flange is embedded in adjacent concrete. The skirt has a knock-out web at its smaller diameter end portion and the seal and closure member may thus be employed selectively as closure members for apertures in distribution boxes and the like and as seals for pipes in communication with the box interiors.
